I have installed it and loaded the book I'm currently reading on it. It synced to the last page I read automatically. I still prefer reading on the Kindle itself. I think it will be very convenient to read a few pages when I don't have my Kindle with me.

Just downloaded it, got a sample chapter - glad to see the app. However, there is absolutely no control - You must swipe horizontally to change pages, you can't adjust margins or background colors. Also, there is no iPhone optimized Kindle store. All that said, I think this is pretty cool - those of you with Kindles and iPhones are going to love the sync feature, I'm pretty sure.

I've plowed a few bucks into Kindle format reference books of various ilks and I've already transfered some of them to the iPhone. Erica Sadun's iPhone programming book for example is kinda handy to have on the iPhone.

But I miss the 5 way navigator, clipping, annotation and search features. Digging around inside the reference tomes is a bit awkward right now.

They've clearly tried to target it as a "casual reader" compared to the Kindle's more in-depth support for research etc...
